i have a http proxy, i use it well with my browser.but for seo panel, i always get "not activie" when i check status.i found some websites from internet and almost non of them can be used in seopanel, but most of them can be used with a browser.i think it is the bug of seop panel

I have the same issue. I am using squid proxy and on status check the go inactive. I opened the file and only see ONE place where that exact line is. I did as recommended on that one line and saw no change.
